I think at first when they first get away, yes, I think they say screw you. After they fly off and realize that they don't know where the food is, and how to take care of themselves, then I think they change their tune. Trouble is, they don't know how to come back. Often times they go off and die, but some do make it. South Florida has all kinds of non-native birds flying around.
True story. One day I was at work, and on my lunch break. A bunch of us were sitting outside by the loading docks. A grey cockateil landed on the asphault where the trucks back up to the docks. He was pecking at the ground like he was hungry. I walked down the steps, and got right up next to the bird. I squated down very slowly, and then I stuck out my pointer finger to him. He climed right on. I then put my thumb over his feet so he couldn't fly off. Yeah, he bit me a few times, but we took him inside, and found a box to put him in. I gave him to a girl that worked there, and her kids loved it. It was clearly someone's pet that got loose, and I don't think it could care for itself.
Sad part about your bird is, if it's that young it needs to be found fast utherwise it may not do well. And then there is the winter up where you live. So, I hope you find him.
